A new example of an algebraic surface with canonical map of degree 16
- 61 Downloads
In this note, we construct a minimal surface of general type with geometric genus \( p_g =4 \), self-intersection of the canonical divisor \( K^2 = 32\), and irregularity \( q = 1 \) such that its canonical map is an Abelian cover of degree 16 of \(\mathbb P^1\times \mathbb P^1\).
